12 Claims. (Cl. 56--3i7) This invention is a division of our applicationfiled June 4, 1953, Serial No. 359,463, and now Patent No. 2,904,- 950and relates to a raking device such as a side delivery rake or swathturner having rake wheels which are put into rotation by contact withthe ground, the rake wheels being arranged at an angle to the directionof travel of the device.

An object of the invention is to provide a raking device of the abovedescription in which the construction of the mobile frame carrying therake wheels is simplified with a corresponding reduction in weight.

A further object of the invention is to provide the ralo ing device witha support or supports, which are relatively small, light, carry arunning wheel, and are resiliently mounted.

Further objects, features and details of the invention will appear fromthe following description with reference to the accompanying drawings inwhich an embodiment of the raking device according to the invention hasbeen shown by way of example in which:

FIGURE 1 shows a plan view of a side delivery rake and swath turnerwhich is combined with a tractor;

FIGURE 2 is a side elevationv of a running wheel used in the machineaccording to'FIGURE 1; and

FIGURE 3 is a plan view of the machine according to FIGURE 1 shown inthe side delivery position indicated by the dotted lines in FIGURE 1.

The device shown in FIGURE 1 comprises a tractor 5i; which is combinedwith a side delivery rake and a swath turner. The position of themachine as a swath turner is indicated in FIGURE 1 by the full lines.The side delivery position is shown in FIGURE 3. The parts in EEG- URE 3have been identified by the same numbers as in FIGURE 1, with theaddition of a d to the reference numerals.

The tractor 59 carries a number of rearwardly extending lift bars suchas rods 51 and 52, the ends of which are interconnected by a laterallyarranged rod-like member constituting rod 53, which, as will be seen,constitutes a pivot means for the raking attachment interconnectedthereto. In the center portion of rod 53 is a coupling, of which parts54 and 55 are rotatable with respect to each other, about an axisparallel with the longitudinal axis of the tractor, as shown in PatentNo. 2,446,584. Part 54 is fixed to rod 53. A first frame part comprisingtube 56 is hingedly connected at hinge 57 to part 55. The longitudinalaxis of hinge 57 is substantially vertical. Tube 56 may be fixed inrespect to its angular position with part 55 by means of pin 57' in anyone of a number of positions. Means of this nature for securing angularposition are well known to the art as exemplified by Patents Nos.1,362,154, 1,490,758, 1,701,107, and 2,577,145. To the tube 56 is weldeda second frame part comprising tube 58, and the angular position oftubes 56 and 53 is secured by strut Tubes 56 and 58 together with theassociated strut 59 comprise frame 49. The free ends as and er of tubes5d and 53 are bent vertically downward and carry axles constitutingshort extensions as and 61', one of which, so, is shown in FIGURE 2,which are rotatable, about vertical axes and may be locked in positionby a pin, not shown, that will prevent relative rotation of parts dd andso, as shown in Patent No. 2,447,354. The hubs,

62 and 63, of the rake wheels 64 and 65, as well as bushings 66 and 67are rotatable about said extensions 60 and till. Said bushings dd and d7carry cranks, 68 and 69, and the rake wheels 7% and 71 are rotatablymounted upon the crank pins of said cranks.

The extensions of so and 61' carry at their ends vertical tubes 72 and73, each forming part of the support structure for their respectiverunning wheels 74 and 75. This is more clearly shown in FlGURE 2, whichillustrates the support structure for running wheel 74. In the figureare shown the extension as, the vertical tube 72 and rod 7e rotatabletherein, and abutting at the top against the bottom end of the threadedrod 77. This threaded rod '77 may be screwed upwards and downwardswithin the upper part of tube 72 by means of handle 73, thus adjustingthe height of extension 60 above the ground. Running wheel 74 runs in afork 7% which is pivotally connected on the bottom portion of rod 76 bymeans of a horizontal pivot 76. To fork 7 9 is also hingedly connectedthe bottom portion of a rod 8% which is arranged parallel to rod 76. Theupper portion of rod 8h has an adjustable nut 81 which holds a helicalspring 82 between said not 31 and a plate 83 rigidly connected to red76. Rod t extends through an opening in plate 83. When the wheel 74 ispushed upwards, whereby fork 79 turns in a clockwise direction, asviewed in FIGURE 2, about the pivot on rod 76, spring S2 is compressedby rod being pulled downward, and the desired supporting resiliency isthereby obtained. Rod 76 is rotatable in tube 72 and the running wheel74 is thus self-adjusting in the manner of a conventional coaster. Therunning wheel is connected to the tube 73 in the same way as runningwheel '74 is to tube 72.

For transport, the swath turner or side delivery rake as the case maybe, is lifted integrally from the ground. As will be understood by thoseskilled in the art, parts 54 and 55 and rod 53 may be secured againstrotation as rods 51 and 52, which constitute lift means, are movedupwards. In this connection, any suitable means known to those skilledin the art may be employed to secure parts 54 and 55 and rod 53 againstrotation. Thus, for example pun poses only, means for securing a partsimilar to rod 53 against rotation is disclosed in Patent No. 2,446,584,and parts 54 and 55 may be secured by clamps such as shown in PatentsNos. 2,241,089 and 2,640,717, or a jack as disclosed in latent No.864,166. in reference to Patent No. 2,446,584, it will be noted that thelifting means therein employed is equivalent to the lifting means forthe raking attachment in thi invention.

The above descriptions and drawings disclose a single embodiment of theinvention and specific language has been employed in describing t.-efigures. t will, nevertheless, be understood that no limitations of thescope of the invention are thereby contemplated, and that variousalterations and modifications may be made and equivalcnts employed suchas would occur to one skilled in the art to which the invention relates.
